Processing received RA with Router Lifetime=0

[Interoperability Test Scenario]

Last Update: February 26, 2000

This scenario verifies interoperability when the target HOST is attached to the model network.

Subjects:
Verification of the processing of the target host receiving RA with Router Lifetime=0.
Verification Points:

A certain router forwards packets but transmits RA with Router Lifetime=0. Therefore the target HOST that receives the RA can't configure the ROUTER as one of default routers. However the target HOST tries to transmit packets to certain destination behind the router via a different router. But the host receives Redirect message from it, and the target HOST gets reachability via the certain router.
